Question

A video game club at the community center hosts a tournament. The total number of participants is 30. Write pseudocode for a python program that takes in input the name of the player and the number of points each player got total and display the top 3 players’ scores.

Answer 1

PSEUDOCODE

A function getTopPlayer which has four paramters (all lists): names, points, topNames and topPoints
   Get maximum points from list of points using max(built-in function) and store it in top variable
   Get index of that top (highest) points from topPoints list
   Append name (that is found at index in names list) in topNames list
   Append points (that is found at index in points lits) in topPoints list
   Remove name at that index from names list using pop (built-in function) of list
   Remove points at that index from points list using pop(built-in function) of list

create an empty list named 'playerNames' to store names of players entered by user
create an empty list named 'playerPoints' to store number of points for each player entered by user
create an empty list named 'topPlayerNames' to store names of top three players
create an empty list named 'topPlayerPoints' to store points of top three players

for i=0 to 30:
   print the player number
   Take input 'Enter name of player: ' and store it in variable name
   Append that name in the playerNames list
   Take input 'Enter number of points: ' and store it in points variable
   Append that points in the playerPoints list

print 'The Top Three Players'

for i=0 to 3:
   calling getTopPlayer function with passing playerNames, playerPoints, topPlayerNames and topPlayerPoints as paramters
   print 'Player#' and name of player using topPlayerNames[i] and points using topPlayerPoints[i]
     

PROGRAM CODE (Proof Pseudocode is working!!)

def getTopPlayer(names = [], points = [], topNames =[], topPoints = []):

# Getting index where points are highest because later to display that top player name and score

top = max(points)
index = points.index(top)

topNames.append(names[index])
topPoints.append(points[index])

# Removing that top player name as well as points because next time to get further top player with highest points

names.pop(index)
points.pop(index)

# A list of Player names and their points

playerNames = []
playerPoints = []
topPlayerNames = []
topPlayerPoints = []

# Taking input name of 5 players instead of 30 as a sample

for i in range(5):
print("---Player#", i+1, "---")

name = input("Enter name of player: ")
points = input("Enter number of points: ")

playerNames.append(name)
playerPoints.append(points)

# Showing top 3 Player names stored in topPlayerNames and topPlayerPoints lists

print('\nThe top three players')

for i in range(3):

# Calling getTopPlayer function
getTopPlayer(playerNames, playerPoints, topPlayerNames, topPlayerPoints)

print('(Player#', (i+1), ')-> Name: ', topPlayerNames[i], ', Points: ', topPlayerPoints[i])

PROGRAM CODE SCREEN SHOT

def getTopPlayer(names[], points.bl, topNames topPoints ...): # Getting index where points are highest because later to display that top player name and score 4 5 top = max(points) index = points.index(top) topNames.append(names[index]) topPoints.append(points[index]) 6 7 8 9 # Removing that top player name as well as points because next time to get further top player with highest points names.pop(index) points.pop(index) # A list of Player names and their points playerNames = [] playerPoints = [] topPlayerNames = [] topPlayerPoints = [] 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 # Taking input name of 5 players instead of 30 as a sample for i in range(5): print("---Player#", i+1, "---") name = input("Enter name of player: ") points = input("Enter number of points: ")

playerNames.append(name) playerPoints.append(points) # Showing top 3 Player names stored in topPlayerNames and topPlayerPoints lists print("\nThe top three players') 28 29 30 31 32 33 34 35 36 37 38 39 40 for i in range(3): # Calling getTopPlayer function getTopPlayer(playerNames, playerPoints, topPlayerNames, topPlayerPoints) print('(Player#', (i+1), ')-> Name: ; topPlayerNames[i], ., Points: :, topPlayerPoints[i]) 41
